In thedrawngs like referenceV numerals indicate-likeparts.

AIn the drawings reference numeral l indicates a pedestal having-a base"2,'bothA 4of which are hollowfthe pedestalbeing-.open at the top andr bottom. Onlthe top of the pedestal is a plate j On the plate 3 is fastened a pedestall 10,"which pedestal i is fastenedl'toi therplate'3'by"screws I l which are inserted through the plate from below. The pedestal I is expanded at the top to form a head I2 having the horizontal grooves I3 and I4 formed therein. On top of the pedestal I0 is mounted a bearing block I5, the lower edge of which has flanges I6 and I1 thereon which engage in the grooves I3 and I4. This bearing block slides freely forward and back in the grooves I3 and I4 and its travel is limitied as follows: In the flange I6 on one side is formed a long recess I8, the length of which is shown` in Figure 3, and the shape of it is shown in cross section in Figure 8. Into this groove extends a screw I9, which loosely engages in the groove and against which the shoulders 25 and 2| on the ends of the flange I6 at either endqof the groove abut, and by which the forward andV back movement of the bearing block on thehead ,I2l .is limited. When the screw I9 is removed, the' bearing block may be removed from the head and pedestal.

At the top of the bearing block is formed aV bearing which is adapted to support a bolt 22. Pivoted on this bolt is the hollow head 23, which has the shape of an inverted shell. This head is provided with arms 24 and 25 which engage on either end of the bolt and on each side of the bearing head I5. This bolt is fastened in place by the set screw 26, which keeps itfrom turning. The end of the bolt is provided with a groove 21. On the lower end of the bolt, as shown in Figure 2, is provided a helical spring 28, one end of which engages in the groove 21 and the other end of which engages in the head, as indicated at 29. The object of this spring is to lift or assist in lifting the head 23 on `the pivot bolt 22, so that it can be easily swung up from the lower position shown in Figure 3 tothe upper position shown in FigureA 1, in both of which positions it is locked by a bolt 30 which engages in sockets 3I and 32 formed in the bearing block On the under side, as shown in Figure 3, is provided a series of downwardly extending projections or lugs 4I. The location of these lugs corresponds to the position of similar lugs 42 formed on the rubber cushion pad or plate 43, the position of which lugs 42 is shown by small circles on Figure 6. As shown in Figure 6, 32 of these circles appear, it being understood that 32 of these lugs are formed on the rubber cushion pad or plate 43 and 32 of these lugs 4I are formed in the hollow head to correspond, which head is made preferably of aluminum and is a single casting. l

Projecting inwardly from the sides of the hollow head are the ribs 44, 45, 46, 41, and 48, between which engages the edge of the rubber cushion' plate 43 with a sliding engagement and by which it is held in position, and between it has a limited up and down movement. Between the lugs 4I and 42 is provided helical springs 49, 32 of which are used, spaced or positioned to correspond with the small circles in Figure 6. These springs are made preferably of bronze wire and are preferably all alike. This plate is normally convex on top and convex on the bottom, as is shown in cross section in Figure 5. It is hollowed out lengthwise at the right in Figure 3, or at the heel end, to accommodate the steel shank of the shoe. Its shape at the right hand end is shown in Figure 1l.r

Below the rubber cushion plate 43 isprovided the heating unit 5U, which consists of a flexible rubber plate having an electrical heating element contained therein and also having a metallic grid contained therein. The electrical heat` ing element is made of a stock high-resistance In its lowest position this bolt engages with the socket 32 and in its highest v.position it engages with the hole 3l by which it is locked in its highest position, it being understood that the socket 3| is shown in Figure 2 and the socket 32 is shown in Figure 3. The bolt 30 can be moved longitudinally in thehead by the pivoted handle 33, which handle is provided with the hubs 34 and 35 on either side thereof, in which hubs are provided recesses 36. On the forward end of the bolt 30 is mounted a pin 31 extending laterally on each side thereof and engaging with these recesses and by which the bolt can be movedVV forward of `back on the swinging of the handle 33. A hollow space 38 is provided vin the head in which is provided a helical spring 39 surrounding the bolt 30. This springpresses against a pin 40 carried on thebolt and normally serves to push the pin to the left in Figure 3, or into the position making locking engagement with the sockets 3I or 32 on the bearing head I5. The movement of the handle 33 upward from the position shown in Figure 3 draws the bolt 33 out of locking position and also lifts the head from the position shown in Figure 3 to the position shown in Figure l, in which position it is again locked bythe engagement of the bolt 30 wire of suitable diameter coiled into a helical coil and is laid in the rubber in the shape indicated in dotted lines in Figure 7 and is vulcanized therein. This wire is indicated by the reference numeral 52.

Suitably spaced from the resistance wire is a metallic grid made up of strips of thin spring steel about 15% of an inch wide. As shown in Figure '1, 32 of these strips are laid crosswise parallel to each other, and these strips are indicated by the reference numeral 53. These strips are spaced about 1/8 of an inch apart. Across these strips and running lengthwise of the heating unit are similar parallel strips of spring steel, live of which are used, and these strips are indicated by the reference numeral 54. The strips 54 make contact with the strips 53, so that heat will iiow and be evenly distributed throughout the grid.

'I'he heating wire and the strips 53 and 54 are all molded together in the rubber plate 50, three layers of rubber being used to make the heating plate 53, the heating wire being vulcanized between the first and second layers and the spring steel grid being vulcanized between the second and third layers, and all constituting a single plate with the first layer on the bottom and the third layer on top. In longitudinal cross sec-- tion this plate 5I! is normally shaped as is shown in Figure 3, and in transverse section is substantially straight in cross section. Under pressure this plate 50 conforms as near as may be to the shape of the under side ofthe plate 43. The springs 49 and these two plates 43 and 56 are assembled into the head, and are all held in place by the horseshoe plate 55, which is fastened to the ends of the ribs 44, 45, 46, 41, and 48 by screws, as is shown in Figures 3 and 9.

Inside of the pedestal I is pivotally mounted a lever 60 having a treadle 6I onthelower outer L end thereof. This treadle rocks on a bearing 62. This treadle carries a lug projecting downwardly therefrom, on which is a bearing 63 to which is connected a link 64 which is moved forward and back by the rocking of the treadle 6| on its bearing. V Pivotally mounted on the lever 60 is a pawl B5. The lower end of this'pawl is connectedto the. link 64 and is moved back and forward on the pivot 66 by the rocking of the pedal 6l. The pawl 65 lengages with the ratchet teeth 6l formed on the inside of the pedestal, and by these ratchet teeth the lever 60 can be stopped in any one of four positions as indicated by Athe four teeth. The pawl 65 is U-shaped and the ratchet has two sets of teeth, of four teeth in each set, with which the two upper ends of the pawl engage. This is shown in Figure 10.

Mounted to lslide in the bosses 4 and 5, shown in Figure 3, is the stem 10. This stem is kept from turning by means of the spline 1I, which permits a free up and down movement to the stem l andholds it against'turning. On the stem 'lil is fastened a collar 12. The stem passes through a plate l3 supported on a flange 14 formed in the pedestal. Between the plate 13 and the sleeve l2 is carried a compression spring 'l5 which normally tends to lift the stem l0 and hold the stem in its highest position.

A link I6 is provided connecting the `lower end Yof the stem to the lever 60, by which the stem is drawn down and the spring 15 is compressed. When the lever 60 is released, the spring 15 expands and pushes the stern l0 up. It pushes the shoe up against the heating pad 56 and holds it there with sufficient force to mold the sole to the shape of the shoe and secure the proper heating effect. The springs 49 are compressed to varying extents so that the cemented surfaces are brought together firmly throughout the whole area. While this pressure is on the heating pad 50 will be bent to conform to the shape of the pad 43 and the shape ofthe sole.

Pivotally mounted on the inside of the pedestal is a cylinder "Il, in which slides a piston carried on `the link 18. The piston compresses the air in the cylinder 11 andvacts as a'shock absorber to keep the spring 15 from lifting the's'tem 1l] toofabruptly. l

On top of thestem l0 is 'provided the jack 80, fastened on the stem by aA set screw 81.

On one end of the jack is provided a holeA or socket 82 shown in Figures 2 and 3. 'I'his slot or socket is adapted to receive the head of an eyescrew'83 that is fastened in the'wood last 84 that supports. the shoe 85.- On the other end of the jack is provided a block 86 mounted to slide in the grooves 81, as shown in end elevation at the bottom of Figure 5. On the side is a handwheel 88 having a set screw thereon. By turning this handwheel the set screw is caused to 'lockthe sliding block 86 in any desired position. lThe block 86 is provided with two upheld in place in the blockv 63 `and onwhich it can move laterally or transversely.

5U will be bent to conform to the shape of the v shoe as defined by 'the "last in the shoe and as defined by the 'ultimate shape of the bottom of the pad 43. 'I'he springs49 will be compressed in so doing, so that a sufficient pressure will be distributed over the whole of the sole of the shoe. This pressure may not be uniform, but it will be ample in each part of the sole for the purpose.

It will be understood that under. pressure the last and sole will yield the least and the two pads and springs will yield the most. 'As is shown at the rightin Figures 3 and 4, the pad 43 is .provided withvone row of lugs 42B, which are extra high or long, and another row of lugs 42A, which are of intermediate height or length, so that the topof these lugs will hold -the bottom of the springs lnormally under about the same compression as the springs in the middle ofthe pad are held. A separate lug is used for each spring, instead of making the Whole pad extra thick at this place so that the thickness of the pad 43 itself will be uniform-throughoutand -it will havethe same exibility at the right l-hfand end as it will `in the intermediate parts thereof.

With the shoeand sole in place with the Vsurfaces properly coated with cement, the pressure is applied. The current is then turned' into theheating coil 52 and the pad 50 will be heated thereby. The spring steel members-'53 and54 will conduct the heat along the lpad and vacross the pad and distribute it evenly-throughout the` pad- 50, so that'the sole of the shoe will be evenly heated throughout and will therefore cause the cement to set and fasten the sole on the shoe in theshortest time and most eicient manner.

In adjusting the apparatus for cementing the sole, the bearing head I5 is moved back'or forth,

as may be desired, so `that the right-hand end 56a of the rubber pad will engage-'in the recessL that isfprovided in front of the heel ofthe shoe. 'I'his bearing head l5 slides freely in the grooves i3 and i4 andvwill remain in any position' desired while the pressure is being applied to the sole of the shoe, or Will even adjust itself to some extent to the desired position.

As shown in Figure 3, the pedestal lllis hollow and contains an electrical thermostat control unit |00, which is coordinated with the heating pad 50. In this control is a thermostatblade having a resistance coil thereon through'which passes right holes therein 90, 90 lwhich are not threaded.

dove-tailed in the.groove.94 and .by;which it-is.

the current that heats-the pad 50. This heating coil onthe thermostat blade-is Iin series with a snap switch IUI through which the current-goes to the heating element of the pad 50. thermostat blade has been rcalibrated so that when the'temperature of the pad has reached thedesired point, the thermostat blade will bend far enough to cause the snap switch 'IUI to open. When the thermostat blade has heated up to the desired point and has bent far enough, 'it can Ybe assumed that the temperature of'the padl 50 has' reachedthe desired point for causing the cement This block is l tapered from front to back as is shown in Figthermostat blade |09 and the snap switch |0| act to open the circuit and prevent the temperature of the pad 50 from going higher. In this way overheating of the sole and of the cement is avoided.

For the purpose of controlling the supply of current furnished to the heating unit of the head, I use the electrical connections shown in Figure 14. As shown inFigure 14, terminals |05 and |05 are used to 4supply the current from an ordinary 110 volt line. From the terminal |05 the current flows thro'ugh the line |01, and through a toggle switch |08, and through the resistance coil on the thermostat blade |09 which is heated by the passage of the current.

This thermostat blade bends as it is heated, and the free end of it makes contact with the small push button on the snap switch |0|. When the big push button I is pushed to the left, the small push button ||0 on the vother side of the snap switch is pushed to the left. When the blade |09 heats up, the end of it pushes against the push button I I0 and moves it to the right, and the mechanism in the snap switch |0| releases the button I, which is moved to the right, opening the circuit and stopping the iiow of current to the heating unit.

The block |0| is a commercial unit made by the C. F. Burgess Laboratories, Inc., Freeport, Illinois, and formerly of Madison, Wisconsin, and is referred to as a Micro switch. This unit is a modification of the snap switch shown in Patent 1,960,020, issued May 22, 1934 to McGall, and constitutes no part of my invention. The unit is marked with Patent Number 1,960,020.

The movement of the thermostat blade |09 is regulated by the adjusting screw ||2, shown in Figure 3. By advancing this screw to the left from the position shown in Figure 3, the thermostat blade will be moved away from the button ||0 and it must then heat up more before it has moved far enough to move the button ||0 and throw the switch.

From the block |0| the current ows through the conductor ||3 to the post ||4. The heating unit 52 is connected to the posts ||4 and |06. A lamp is connected between the posts |06 and ||4.

In the ordinary operation, after the shoe is in position and the head 23 is brought down thereon, the operator pushes the button to the left, which closes the switch. The operator then turns the switch |08 and the current begins to iiow through the heating unit and at the same time the lamp I5 lights up and the light thereof shines through the red lens llt. After the thermostat blade has become heated up to a certain extent, it bends and presses on the button ||0 suiiciently to cause the mechanism in the block |0| to open the circuit and push out the button it being understood that the device'operates as a snap switch. Until the circuit is broken', the current passes through the heating unit 52 and raises the temperature of it, and after the circuit is broken no more electric energy is furnished to the heating unit and thereafter it begins to cool off.

'I'he setting of the thermostat blade determines the length of time that the current flows through the heating unit and xes the temperature to which it rises, and the extent to which the cemented sole is heated thereby, it being understood that the temperature should be limited to about 130 degrees Fahrenheit. The length of time durheat should'be limited to vabout 15 minutes, a1- though experience may increase or decrease the time `of theheating ef'ect and the temperature used. y

In Figure 11 I have shown an endview of the head 23, viewed from the right in Figures 2 and v 3. In this View the normal position of the heating pad 50 and the rubber cushion plate 43 is shown, it being understood that this is the position that the parts foccupy when the head is raised and the parts are not pressing against the shoe.

In Figures 12 and 13 I have shown a rubber cushion plate that is a modification of the form shown in Figure 6. As shown in Figures 3 and 6, the lugs 42 have a flat top, while in Figures l2 and 13 the corresponding lugs-|25 are rounded on the top. In the open space in the middle of the cushion plate I provide a rib |25, which gives extra strength to the center of the pad.

Menslshoes are usually made with a Goodyear welt, and this is also true of some womens shoes and childrens shoes. The welt is used so that the sole can be attached to the shoe by sewing it to the welt, If thesole is cemented to the shoe sewing is unnecessary, but it so happens, that the welt ovefhangs the last and will not be supported thereby firmly enough so that the welt and the edge of the sole can be firmly held together under pressure To support the welt so that it will stand up when pressure is applied to the sole, I provide the special form of welt support shown separately in Figure 1'7 and shown applied to awelt shoe in Figures 15 and 16. This welt support comprises two short links |30 and |3|, placed parallel to each other. Between the opposite ends of these links are pivoted the arms |32 and |33, the pivots being located at |34 and |35. Each of these arms comprises a long extension |36 and |31 .on one side of the pivot, which is adapted to engage under the welt, and a short extension |38 and |39 on the other side of the pivot.

Pivotally mounted between the two links |30 and |3| is a stud |40, around which is provided a helical compression spring |4|, which is located between the short arms |38 and |39. Bearing against this compression spring is a sleeve |42, which is provided with grooves |43 on the opposite side thereof in which the short arms |38 and |39 engage. .On the outer end of the stud |40 a wing nut |44 is threaded. `By turning this nut the ing which the cemented sole is exposed to this sleeve |42 isforced to the left, as shown in each of the Figures 15, 16, 1'7, and 18, compressing the spring |4|. As this sleeve is moved to the left it reacts on the.short arms |38 and |39, forcing them apart and drawing together the long arms v|36 and |31 so that they engage closely under the welt. These arms are not only curved, as shown in Figure 17, but are beveled toward the left hand end as shown in Figure 19, so that the beveled edge can engage between the welt and the upper of the shoe and firmly seat itself against the edge of the last contained in the shoe, and thus firmly support the welt so vthat it will not yieldto the pressure on the sole during the cementing operation. Pivotally mounted on the arms |36 and |31 at |45a and |451:I are the supporting'blade's |45 and |45, which blades lcan be swung inwardly from the position shown the welt cannot be advantageously engaged by the arms |36 and |31. I

On the outer ends of the arms |36 and ,|31 extensions |41 and |48 are pivoted. These extensions are supported by the pivots |41a and |48a. The ends of these extensions are connected by a helical spring |49, which spring is permanently attached to the end of extension |41 and is adjustably attached to the extension |48. The extension |48 is provided with a series of openings "|50, and |52, connected by narrow slots.

On the end of the spring |49 is a button which can engage in either one of the openings |50, |5|, or|52. This button has a smallA stem that engages in the opening |50, |5I, or |52, by which it holds itself in place in either of the openings. By lifting the stem of the button out of the opening the button and spring can be moved from one opening to another, and will then lock itself in place by engaging the stem of the button with the next opening. In this way the tension of the spring |49 can be increased or diminished sothat it will flt snugly around the toe of the shoe and will support the welt at the toe of the shoe, and will also serve to hold the extensions |41 and |48 in firm engagement with the welt.

This welt support is put in place as follows: The wing nut |44 is screwed back so as to give free play to arms |30 and |31. The spring |49 is placed in position on the toe of the shoe, and the arms are then brought into place between the welt and the upper, and the links |30 and |3| are swung up behind the heel of the shoe, and the wing nut is then screwed forward, causing l the various parts to take a rm hold on the shoe that will hold the welt in place against pressure.
